2849.20.20.00 - In grains, or ground, pulverized or refined

This classification, 2849.20.20.00, specifically addresses silicon carbide (SiC) that has undergone processing beyond its crude form. It encompasses silicon carbide that has been manufactured into grains, ground to a desired particle size, pulverized into a fine powder, or further refined to enhance purity or specific physical characteristics. These processed forms are typically intended for direct use in industrial applications where precise particle size and morphology are critical for performance.

This category is distinct from its sibling, 2849.20.10.00 (Crude), which covers silicon carbide in its initial, unprocessed state, often as lumps or a rough aggregate. While both originate from the same chemical compound, the key differentiator here is the degree of physical transformation and refinement. Products classified under 2849.20.20.00 have been intentionally altered in form and often in purity to meet specific manufacturing or application requirements, distinguishing them from the raw material.

As this is a leaf node within the HTS, there are no further subcategories for this specific classification. The focus remains on the final physical state of the silicon carbide—grains, ground, pulverized, or refined. Examples of such products could include silicon carbide abrasives in various grit sizes, fine silicon carbide powders used in advanced ceramics, or specially refined silicon carbide for semiconductor applications. Classification at this level hinges on identifying the evident physical processing that has occurred to the silicon carbide.
